To all 107mm t may concer/H,

Be it known that I, HANS PRYM, a subject yof Germany, and residing` atStolberg, Rhine State, in the State Vot' Prussia, Germany, have inventedcertain new Vand useful Improvements in or Relating to a Machine forMounting Press Buttons on Cards, of which the following is aspecification.

The invention relates toA a machine lfor mounting press buttons on cardsor the like, provided withk trame plates carried by an endless chain,the lowerparts of the press buttons, the cards and the'upper part-s ofthe press `buttons being consecutively placed on the said plates beforethey arrive ,at `a press which joins together the press button parts,and consists in the press button parts and the cards being` placed. onthe frame plates, that is to say the press button parts withdrawn fromthe .supply conduits and Vthe cards from the card case or container,

by the movement of the endless chain or of the 4frame plates carriedthereby., Inv that` way an accurate 'and reliable fitting to- `gether of`the press button parts and cards is ensured.

A constructionaccording to the invention is illustrated in theaccompanying drawing in which- Figure 1 is a side elevation and -Figure2 a cross-section at the pointV where'the press is situated for joiningtogether parts of the .press button2 Figure 3 is a partial longitudinalsection, on an -enlarged scale, through the supply `conduit or channelfor the'upper parts of the press buttons, and

Figure 4 is a longitudinal section through the supply conduit for thelower parts, whilst Figure 5 is a. front elevation of Figure 3. Figure6' is a jcross-section through the card delivery device, and

Figure 7 isa Aplan thereof.

Two spindles 2 and 3 mounted in onen frame 1, carry chain wheels `4' and5 for an endless chain 6 constituted by links' of equal size connectedtogether by bolts.

Each link carries Va plate 7 with pins 8 arrangedV at the-:longitudinaland transverse distances of the perforations of a press button card. Toensure eilicieiit'guiding, the

plates 7 travel in ,grooves 9 in the frame 1 (see also Figure 6). Abovethe chain the supply channel 10 is arranged vfor the lower Vends withgrooves 13a,

Ation at the moment,

parts, and the supply channel 11 for thel and 14 (Figures 3-5) mountedon a transyerse member or carrier 12 and projecting into the supplycliannel 10 or 11. The locking pins 13 which are provided at the lowerare mounted in an approximately vertically adjustable manner in thetransverse carrier 12, and are forced by springs 15 into the channel 10or 11 so that they prevent the lowest press button part contained in thechannel, from escaping, and hold it in an oblique 'positionin thechannel, the' hood or cap of the button being held in the groove 13a.The locking pins 14 are arranged in a horizontally adjustable manner andare pulled slightly into the channel in the lateral direction by spring16, so that the press button part calinot emerge at the side. Only whenthe ,locking pins 13. 14 are forced back, the

.press button part which is the lowest posican escape from the channel10 or 11.

Between the supply channels 10 and 11 the card container or case 17 isarranged to support a supply of the perforated cards 1&5 (Figures 6 and7) which rest on a support 1'?a and are elevated. by springs 17D. 19 isa slide for advancing of the cards, which is advanced owing to atappet2O provided on the chain 6, striking, duringl the advance of the latterin the direction of the arrow I, an arm 21 of a double arm lever 21, 23pivoted at 22. Two rubber rolls 24 and 25, the spindles of which aremounted on springs, and which are driven by a toothed wheel 26, advancethe cards supplied to them by the slide 19. At the other side of thechain to the machine frame is secured a bracket 27 into the upper end ofwhich is firmly screwed a bar 28. Under the said bar and pivotallyconnected to it by bars or links 29, is a bar 30 which projects througha slot of the bracket 27 and carries at its outer end a roller 31. Aspring 32 constantly pulls the bar 30 into the upper position shown inFigure 6; its height can be adjusted exactly by means of a set-screw 33.On the bar 30, at right-angles thereto and at a small distance apart,are mounted two plates 34 which clamp between them and hold fast vthecards supplied by the rolls 24, 25. About a. vertical p in a lever 3Gcan turn provided at right# angles with an arm 37. ris soon as, duringthe movement of the chain, a tap pet 3S screwed to thev chain plate 7strikes the arm 2T at the point 39,'the said arm and therefore the lever3G will be turned sideways, and the lever will drive the roller 3l,owing to which the bar 30 will be laterally pulled out of thebracket 27(see the dotted lines in Figure 7) and owing to the-bars 29, turnedvertically downwards.

is an ebonite roll (Figures 1-3) mounted by means ofrsprings immediatelybehind thesuppl-y channel 1l in bearings 4l ofthe frame 1 andconstituted by several discs (one for each series of buttons) mountedloosely and in a freely rotatable' manner on the spin` dle ofthe roll.It is used as a press for joining together the press button parts.l ltssubdivision into single loose discs for the purpose of gradually andlightly pressing Y. the press button yupper parts.

The working of the machine is as follows-:- Y

The chain travels in the direction of the arrow (Figures 1v and 7)', andthe supply channels 10are filled with the lower parts of the pressbutton, and the channels 11 with t Athe upperparts. (if these channelsas many yare arranged Vside by side as there are rows of pins on theframe plates 7. Thevlower parts 42 which areat the'outlet of thechannels 10 at the discharge pOints,'arc iii-such Vanobliqueposition'that the pins 8 of the plates 7 engage by means of their offsetends, y

flower parte ofthe pressibuttons supported with the openings of thebutton caps (Figure 4)-and pull' them out from their holding devices 13,14, the button caps being guided in ythe grooves 13a. Each pin 7 carriestherefore one lower part 42.

In the meantime the tappet 2O has moved the lever 21, 23. v Owing tothat, the slide 19 introduces a perforated card 18 with its front edgebetween the rubber -rolls 24 and 25, and the said rolls introduce thecard between the clamping plates 34. The'lever 21,

v28 is pulled back by a spring (not shown) immediately after the slidingoff of the tap-V During the continued movement of the chain, the vtappet38 provided on the frame plate 7, strikes at 39 the arm C37 and by meansof the lever'36 andthe roller 31, pulls the bar 30 out of the-bracket27, the said bar turning downwards and pressing on the card 18 held -bythe clamping plates 34. At the same momenthoweverduring the travel lingof the chain the tappet 38 arrivesat a slot 43 of the bar 30 and pushesthe card 18 out of the clamping `plates 34. The card therefore will bepressed down by the bar 30 on the pins 8 travelling` under it, with thelower parts 42 mounted on them, so that-- roll 40 which, by the pressureof its spring` controlled spindle, presses the button caps intoeachother and thus secures them to the card. The finished cards thendrop, during the continued movement v'ofthe chainover the chainwheel 5,into a collector tank.
